UNITED STATES PATENT OFFICE.

AUGUSTUS E. HARDY, OF MISHAIVAKA, INDIANA.

MACHINE FOR FORMING FELT BOOT BLANKS.

SPECIFICATION forming part of Letters Patent No. 421,275, dated February11,1890.

Application filed November 1, 1889. Serial No. 328,897. (No model.)

To all whom it may concern:

Be it known that I, AUGUSTUS E. HARDY, of Mishawaka, in the county ofSt. Joseph and State of Indiana, have invented certain new and usefulImprovements in Machines for Forming Felt Bootl3lanks; and I do herebydeclare'that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form part of thisspecification.

This invention relates to certain. improve ments in machines for formingfelt bootblanks, and it has for its objects to provide for wrapping andfelting the felting material as it is delivered from thecar'dinganachine automatically upon the former, so as to pro duce ablank of uniform thickness throughout.

In the accompanying drawings, forming part of this specification, Figure1 represents a perspective view of a machine embodying my invention.Fig. 2 represents a top view of the same, and Fig. Srepresents adetached View of the former upon which the felt is wrapped and felted inthe construction of the blank.

Referring to the drawings, the letter A indicates two standards, whichare provided with bases B, which rest upon and are bolted to the floorof the building in which the machine is located, or to any othersuitable support. The said standards are provided with bearings O forthe journals of the shafts of the rollers D D. These rollers are locatedparallel to each other, and the journals at one end project from theirbearings and are provided with pulleys E, over which passes an endlessband or belt F, so as to cause the rollers to move simultaneously whenmotion is imparted to one. The shaft of the roller D is provided with apulley G, by means of which it may receive motion from a band con neetedwith the driving-pulley of any suit able motor. The rollers D D inlongitudinal section are in the shape of parabolic conoids, their largerends at their peripheries abutting or nearly abutting against eachother.

The letter II indicates a loose roller which is formed in the shape of aparabolic cone, so as to set accurately in the space between the rollersD D, its apex fitting between the the larger abutting ends of the saidrollers. .The roller D is larger in diameter than the roller D, whereby,if desired, a drawing motion is given to the loose roller II when themachine is in operation; or they may be of same size.

The machine is so located with respect to the delivery or dischargeportion of the carding-machine as to receive the felting materialbetween the rollers D and H. The roller H, resting upon the rollers Dand D, is held upon the same by its own weight, and rotated upon thesame by frictional contact therewith, taking up the felting material asit is delivered and automatically wrapping it upon itself. The wrappingoperation effects the felting of the felting material uniformly, andwhen. a sufficient thickness has been produced upon the former or looseroller H it is removed and the felted blank drawn off for subsequenttreatment.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is
